The use of ion beams for forensic analysis
Ion Beam Analysis (IBA) consists of a suite of techniques that offer non-destructive and quantitative elemental analysis of a huge range of materials. They also have higher sensitivity to trace elements than conventional forensic techniques and in most cases require no sample preparation, completely ruling out one potential route of contamination. The use of IBA in criminal casework has been limited thus far due to factors including cost and access to equipment.
In this presentation, an introduction to the basic principles of IBA will be given along with results from work carried out on a range of forensic sample types including gunshot residue, soil particles, glass fragments and fingerprints. In all of these cases, IBA can provide complementary information to the techniques currently used in forensic investigations, maximising the evidential value of each and every piece of trace evidence. We show that for high profile cases, in which police authorities devote substantial resources, ion beam analysis techniques show great promise.
